1. Area & Conversions Here’s a chance to fix your mistakes from the test…

2. #1 You’re given the area of a square… Find the Perimeter First, break apart the area. – We know that Area = l x w. – In a square, the length and width are the same. – So we can say that Area = side x side or A = s 2 – 36 = s 2 Take the square root of both and you’ll get: – Side = 6 To find the perimeter of a square, you add up the four sides. If each side is 6, you add 6 + 6 + 6 + 6 Pick the correct answer!

3. #2 & #3 Identifying area formulas You can find area formulas in your assignment book or your unit tools sheet If you don’t have that with you, you can find them in the back of the math book – there should be some in the desks. Remember: We only studied the area formulas for rectangles, triangles, and circles and we just had rectangles on the screen…

4. #4 Finding ft 2 and converting it to yd 2 Find the area of the room A = 12 x 9 Now, to convert to yd 2, take the number of feet in a yard (3) and square it! (3 2 ) You need to divide by that number to get the correct answer. – Do you know why it was squared? Remember that we square when we’re finding area…

5. #5 The number of servings of punch Yes, this problem is kind of long and involved, but it’s worth it to get the points! The punch is made of 1 gallon of fruit punch and 1 quart of ginger ale. How many quarts are in a gallon? – 4 quarts = 1 gallon! So that means that you have 5 quarts of punch once it’s mixed together. How many cups are in a quart? – 4 cups = 1 quart! So then how many cups of punch will we have? – I’ll let you calculate that one How many ounces are in 1 cup? – 8oz. = 1 cup So that means that one of the servings of punch is one cup, right? So how many servings can you make?

6. #6 Find the area of the trapezoid One of the things you are supposed to be able to do is come up with the area of a trapezoid on your own – so here’s your big chance! This trapezoid can be broken into 3 parts: – two triangles – one rectangle You need to figure out the length and width of the rectangle. The numbers are there for you! (A = l x w) You also need to figure out the base of each triangle. Remember that there are two triangles, so you need to divide! (A = ½ b h ) Add up the areas and don’t forget that there are TWO triangles! 6 in. 10 in. 8 in. 10 – 8 = 2 2 ÷ 2 = 1 b = 1 in. l = 8 in. w = 6 in. h = 6 in.
